The South Coast Air Quality Management District (South Coast AQMD) is sensitive to the ongoing challenges currently facing the public, businesses and other organizations within our jurisdiction due to COVID-19. We are committed to doing what we can to help businesses while protecting air quality, public health and safety.

South Coast AQMD is considered an essential government agency and we are doing everything we can to ensure our core operations continue during this difficult time.

Following advice from the World Health Organization, the Centers for Disease Control and Prevention, and state and local public health agencies, the South Coast AQMD Headquarters building, located at 21865 Copley Dr, Diamond Bar, Calif. is closed to the public until further notice.

However critical functions continue including compliance and enforcement, emergency response, air monitoring, permitting, rule development and response to public complaints. We will prioritize and expedite permit applications from businesses and organizations that are changing operations to assist with the COVID-19 response.

As part of efforts to minimize potential risk and exposure, meetings including Committee and Governing Board Meetings, public workshops and trainings will be cancelled, postponed or conducted online via phone and videoconferencing. Meeting updates can be found on our calendar page or by downloading the South Coast AQMD smartphone app.
